摘要： In a liquid crystal display device, a TFT substrate retains a contact hole that is formed in a passivation film, and is for connecting the TFT and the pixel electrode. And an opposite substrate retains a columnar spacer for ensuring a cell gap, and a columnar projection for misalignment prevention formed at a position corresponding to a position of the contact hole. Accordingly, misalignment between the TFT substrate and the opposite substrate is suppressed, occurrence of uneven brightness due to misalignment between pixel regions and a bright spot caused by shaving of an orientation film is prevented, and a favorable image is obtained.

摘要： An IPS liquid crystal display device intended to prevent generation of second image sticking after generation of initial DC image sticking.An alignment film has a two-layer structure comprising an upper alignment film and a lower alignment film. The upper alignment film is an optical alignment film formed of a polyamide acid ester as a precursor. The lower alignment film has a lower resistance value than the upper alignment film and also has a low photoconductive property. The lower alignment film is formed not using, as a precursor, a polyamide acid using PMDA as the starting material but using, as a precursor, the polyamide acid containing a sulfonic acid group or a carboxylic group, whereby the difference of the resistance between portions undergoing or not undergoing light irradiation in the pixel is decreased and generation of second image sticking can be prevented.
摘要翻译： IPS液晶显示装置，旨在防止在产生初始DC图像残留之后产生第二图像残留。取向膜具有包括上取向膜和下取向膜的双层结构。上取向膜是由聚酰胺酸酯作为前体形成的光取向膜。下取向膜的电阻值比上取向膜低，导光性也低。使用PMDA作为起始原料但不使用含有磺酸基或羧基的聚酰胺酸作为前体，不使用作为前体的聚酰胺酸作为前体而形成下取向膜，由此使得部分之间的电阻差在像素中进行或不经历光照射的情况减少，并且可以防止产生第二图像粘附。

摘要： This invention enables forming a photo-alignment film having a large LC anchoring strength in an IPS type liquid crystal display device. An alignment film is adapted to have a two-layer structure including a photo-alignment film and an alignment film with enhanced film strength. The photo-alignment film is formed of a precursor of polyamide acid ester, 80 percent or more of which is polyamide acid ester including cyclobutane. The alignment film with enhanced film strength is formed of a precursor of polyamide acid. After irradiating the substrate with ultraviolet light for photo-alignment, the substrate is heated. Thus, it is possible to achieve a high LC anchoring strength of the alignment film as the whole for photo-alignment, without degrading the mechanical strength of the alignment film with enhanced film strength.

摘要： The present invention relates to a method of manufacturing a liquid crystal display device having a TFT substrate and a counter substrate, and prevents brightness unevenness from being caused by orientation film thickness unevenness.Orientation films for the TFT substrate 10 and the counter substrate 20 are formed by offset printing that is performed to transfer an orientation film material from a printing plate to the TFT substrate 10. The direction in which the printing plate for an offset printing machine rotates during offset printing is the long-axis direction of the TFT substrate 10 in the case of the TFT substrate 10 or the short-axis direction of the counter substrate in the case of the counter substrate. This ensures that brightness unevenness caused by orientation film thickness unevenness is inconspicuous even when the orientation film thickness unevenness is produced during offset printing.

摘要： In a liquid crystal display device, a light shielding film, a color filter, an overcoat film, and an alignment film are formed in this order on a counter substrate. However, the alignment film is not formed in a seal portion. When the alignment film is subjected to photo-alignment with ultraviolet radiation, a portion of the overcoat film not covered with the alignment film is degraded by ultraviolet radiation. In order to prevent moisture penetrating from the degraded overcoat film from reaching the light shielding film to thereby alter the light shielding film and from causing the peeling of the light shielding film, the color filter is disposed below the overcoat film to block the moisture.
